objection

Runtime Mobile Exploration, powered by Frida.

introduction

objection is a runtime mobile exploration toolkit, powered by Frida. It was built with the aim of helping assess mobile applications and their security posture without the need for a jailbroken or rooted mobile device.

The project's name quite literally explains the approach as well, whereby runtime specific objects are injected into a running process and executed using Frida.

Note This is not some form of jailbreak / root bypass. By using objection, you are still limited by all of the restrictions imposed by the applicable sandbox you are facing.

features

Currently, only iOS is supported with Android support coming soon.

For iOS, objection allows you to:

• Interact with the iOS filesystem, listing entries as well as upload & download files where permitted.
• Perform various memory related tasks, such as listing loaded modules and their respective exports.
• Dump the iOS keychain, and export it to a file.
• Attempt to bypass and simulate Jailbreak detections.
• Perform common SSL pinning bypasses.
• Dump data from NSUserDefaults and the shared NSHTTPCookieStorage.
• Dynamically dump arguments from methods called as you use the target application.
• Dump various formats of information in human readable forms.
• Bypass certain forms of TouchID restrictions.
• Execute custom Frida scripts.

sample usage

A sample session, where objection is used to explore the applications environment:

prerequisites

To run objection, all you need is the python3 interpreter to be available. The installation via pip should take care of all of the dependencies needed.

As for the mobile applications though, for iOS, an unencrypted IPA is needed. If you have the source code of the application you want to explore, then you can simply embed and load the FridaGadget.gylib in the project.

installation

Installation for now is simply a matter of cloning this repository and doing pip install --editable .. This will give you the objection command.

todo:

There is still a ton of work left to do.

• Android support!
• Automatically unarchive keychain items that are bplist00ԁX$versionX$objectsY$archiverT$top
• Detect more argument types in ios argument dumper
• Touchid kSecAccessControlTouchIDAny keychain item experiment
• Implement rpc.exports for the filemanager to help with performance and timeouts
